Sea urchin injuries are caused by contact with sea urchins, and are characterized by puncture wounds inflicted by the animal's brittle, fragile spines. [1]: 431 Injuries usually occur when swimmers, divers, surfers, or fishers by accidentally touching them or stepping on them. [2]
The wound can be allowed to close by secondary intention. Alternatively, if the infection is cleared and healthy granulation tissue is evident at the base of the wound, the edges of the incision may be reapproximated, such as by using butterfly stitches, staples or sutures. [4]
A cobra bite on the foot of a girl in Thailand: Specialty: Emergency medicine: Symptoms: Two puncture wounds, redness, swelling, severe pain at the area [1] [2] Complications: Bleeding, kidney failure, severe allergic reaction, tissue death around the bite, breathing problems, amputation, envenomation [1] [3] Causes: Snakes [1] Risk factors
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.

Maggot therapy (also known as larval therapy) is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into non-healing skin and soft-tissue wounds of a human or other animal for the purpose of cleaning out the necrotic (dead) tissue within a wound (debridement), and disinfection.
Antibiotics may be administered to prevent infection if there is a delay in treatment, if the wound is deep, or if there is a large amount of foreign material in the wound. [3] Pain may be treated with local anesthetic in and around the wound, a regional nerve blockade, or parenteral opiates such as intramuscular pethidine. [3]
Abrasions on elbow and lower arm. The elbow wound will produce a permanent scar. A first-degree abrasion involves only epidermal injury. A second-degree abrasion involves the epidermis as well as the dermis and may bleed slightly. A third-degree abrasion involves damage to the subcutaneous layer and the skin and is often called an avulsion.
